IMPROVEMENT IN HARNESS-CUTTERS VISES.

Specification forming part of Letters Patent No. 209,438, dated October29, 18.78; application filed March 25, 1878.

To all whom 'it may concern:

Be it known that I, WILLIAM P. WOLF- INGTON, of Louisville, Kentucky,have invented a HarneSsOutterls Vise, of which the following is aspeciication:

The object of my invention is to provide for harness-cutters a vise tohold a side of leather while it is being cut into straps.

The nature of this invention consists in making two cone-shaped rollersto roll and slide upon two pins that converge from a standard, the pinsbeing surrounded with coilsprings to keep them atthe ends or apex, andthe rollers having upon the small ends teeth to catch the leather andupon the large ends, respectively, a ange and a groove to interlock eachother, so that their movements are simultaneous.

By reference to the accompanying drawings, in which Figure 2 illustratesthe manner in which the rollers are made, and Fig. l is a perspectiveview of the vise complete, it will be seen that A is a standard, fromwhich two pins, P P, converge nearly together at their ends, one of thembeing screwed into the standard in order to get the rollers off and onwhen desired. B B are the rollers. Upon the large ends they have,respectively, a deep groove, C, and a iiange, D, and are capped towardthe cone end, that being necessary because of the angle at which thepins are set, the ange meshing into the groove deep enough to engageeach other at all points. The

cone ends have teeth I I turned upon their surt faces in the manner ofsaw or ratchet teeth, and the teeth of the two cones are kept oppositeto each other by the interlocking ange and groove, this position of theteeth with respect to each other causing them to take the surest hold onthe leather. Coil-springssurround the pins, forcing the rollers out tothe ends, where they come in contact with each other at the largest partot' the cones, the otherteeth graduating wider apart, so that a thickpiece of leather is more readily caught near the end, while. a thinpiece must be pushed farther back.

The operation of this invention is readily 'seen The end of the sideofleatheris pushed into the vise through the open end E, and thegage-knife the vise closes upon it, and holds it securely. As the strapsare cut oit the side of leather is easily moved laterally by rollingbetween the cones, and may be entirely removed in that way or by forcingback the cones with the hand.

My invention differs from all other kinds of vises, pinchers, and thelike, which have jaws to gripe and teeth to hold, in this, that theteeth are expressly set just opposite to each other instead of meshingin between each other, as is the case in other devices, which would beinoperative or entirely too uncertain in my invention, and that thegreater part of the teeth do not come in contact with each other at allwhen the vise is closed, as is the case in other devices, but have agradual divaricatin g separation, so as to leave the opening E, byreason of which the vise does not have to be opened with the hand inorder to put anything in it, as is the case in other devices, it beingonly necessary to thrust in anything desired to be held.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a vise for harness-cutting and similar uses, the combination ofthe standard A. pins or axes P P, coil-springs a c, and serrated conicalrollers B B, substantially as herein shown and described.

2. In a vise for harness-cutting and similar uses, the serrated conicalrollers, provided with interlocking devices D C, substantially asand forthe purpose shown and described.

3. In a vise for harness-cutting and similar uses, the interlockingrollers or jaws, to open and close by their sliding back and forward inconverging guides, and arranged with their teeth in opposite and gradualdivaricating positions, substantially as and for the purpose hereinshown and described.
